Arguments

x: Age.
i: Effective annual interest rate.
model: Optional survival model name.
...: Additional model parameters.
tbl: Optional life table object for discrete functions.
k_max: Maximum summation horizon for non-terminating models.
tol: Truncation tolerance for non-terminating models.
n: Term in years.

Value

Numeric vector containing the requested increasing or decreasing annuity value.
